T 0 all whom it may concern:

Be it lrnown that I, JACOB W. Rn a citizen of the United States, r atMilan, in the county of Suli 'an and State chine elements and itconsists in novel means for supporting a gear or other member upon ashaft, and for locking this gear the shaft when desired, or freeing ittherefrom so that it canrun idly, and the particular objcct of theinvention is to provide means for rotatably supporting a gear orrotatable member upon a shaft without direct contact therewith so thatthe interior notches or clutch portions of such member do not contactwith the shaft, and do not have any rubbing or rotary frictional contactwith the shaft or the support upon which the gear is mounted, andwhereby the strength of the shaft may be reinforced at the point atwhich the gca r or member is supplied.

The invention is particularly designed for use Where it is desired tomount a gear or rotatable member upon a shaft of small diameter,.without impairing the strength of the shaft. i

I will cigplain the invention in connection with the accompanyingdrawings, which illustrate a practical embodiment thereof and willenable others to understand how to construct and use the same, and theclaims summarize the essential features of the invention for whichprotection is desired.

In said drawings: Figure 1. is a side elevation of the complete device;Fig. 2 is a longitudinal section thereof; .Fig. 3 is a front elevation;Fig. "l is a transverse section on line 4-4 of Fig. 2; Fig. 5 is asection on line 55 of Fig. 4; Fig. (3 is a dctail sectional View showinga slight modification.

Referring to said drawings, 1 designates the shaft upon which I desireto mount the gear or disk and which may be the shaft relativcly to thesleeve 2.

of is an automobile engine. Upon this shaft fitted a sleeve 2- which maybe fastened to the shaft 1 by any suitable means, a key :2 beingindicated in the drawings. The sleeve is closely fitted to the shaft soas to reinforce the same. The sleeve is provided near one end with anannular flange 2 of larger diameter than th sleeve; and the sleeve isprovided with a "longitudinal groove 2 in its outer side. The gear, diskor other rotatable object to be mounted upon the shaft, a gear 3 beingshown, has an axial opening of larger diameter than the sleeve '2 and isprovided on its opposite faces with annular recesses 3 and 3" of largerdiameter than the axial opening. The recess 3? is adapted to receive andfit over the flange 2, and the recess 3" is adapted to receive and litover an annular collar 4 which is fittedupon the shouldered end of thesleeve 2 adjacent the flange 2 and may be fixedly but detachably securedto the sleeve by means of screws or keys '1, as indicated in thedrawings. i

The web portion 3 of the gear 3 lies between the collar 4 and flange 2and has a neat but not close fit against the faces thereof, but theperipheral surfaces of the recesscs 3, 3", have a running fit upon theopposed peripheries of the flange 2 and collar 4 so that the gear ormember 3 is thus rotatably mounted upon the .flange 2 and the collar 4,and while free to rotate thereon, is held from longitudinal movement Theweb 3 is preferably provided with a plurality of notches or slots 3 withany one of which a projection or tooth 5 on a slide 5 mounted in thegroove 2" is adapted to engage. This slide 5 may be shiftedlongitudinally of the sleeve by any suitable means, and as shown isconnected to an annular grooved collar 5 which surrounds the sleeve :2,as indicated in Fig. 1, and can be operated by any suitable shifter. Theflange 9 is provided with an opening or slot 2 for the passage of theslide 5. The slide 5 may be projected beyond the sleeve and through theaxial opening in the gear and an opening l in collar 4, as shown in Fig.2, and has on its outer end :1. lug 5 which when the slide is retractedwill engage the outer side of collar 4 and arrest the slide when theprojection or tooth 5 is entirely disengaged from the gear notches andthen the gear is free to rotate upon the sleeve as described.

It will be seen that when the slide 5 is engaged with one of the notches3 the memher 3 is locked to the sleeve 2 and may be rotated therewith,and if the shaft 1 be the driving member the member 3 will then berotated therewith. If the member 3 be the driving member, then the shaft1 will be rotated with the said member when the key is engaged with oneof the notches 3 as indicated in Fig. 4. It will also be observed thatwhen the slide is disengaged from the member 3 said member is free torotate upon the flange 2 and collar 4 and has no bearing upon the shaftnor does its inner web portion have any direct bearing upon the shaft orsleeve. By means of this invention I am enabled to apply a gear orrotatable member to asmall shaft and lock it to or release it from, theshaft at will by simply shifting slide 5, and the invention can beeasily adapted or applied to a small shaft without weakening the shaft,and indeed it will strengthen same at the point at which the gear ismounted, for the gear is journaled upon the flange and collar on thesleeve which practically forms a long bearing supporting the gear on theshaft, and the sleeve also stifi'ens the shaft at the point where thestrain of transmission of power between the member 3 and the shaft isapplied. If desired instead of the notches 3 the inner periphery of theweb 3 might be toothed as indicated at 3 in Fig. 6 and the slide 5 mightbe provided with one or more teeth 5 adapted to engage any one of theteeth '3 to lock the gear to the sleeve.

Claims.

1. In combination, a shaft, a sleeve mounted thereon having acircumferential annular portion projecting therefrom and a memberrotatably mounted upon the periphery of said annular portion, and havinga web portion with an axial opening and means adapted to engagenon-rotatively the web of said rotary member and lock the same to thesleeve.

-2. In combination, a shaft, a sleeve thereon having a circumferentialannular portion, a member rotatably mounted upon the periphery of saidportion and having a web portion lying beside said portion and meansadapted to engage non-rotatively the web portion of the said member tolock the same to the sleeve when said means is in one position, and inanother position of the means to leave the member free to rotate uponsaid portion.

3. In combination, a shaft, a sleeve thereon having a sircumfesentialannular portion and a longitudinal groove, a gear or member rotatablymounted upon the periphery of said portion and having a web portionlying beside said portion, and a slide in said groove adapted to engagethe web portion of the said member to lock the same to the sleeve whenthe slide is in one position, and in another position of the slide toleave the member free to rotate upon said portion.
